The T.R.I.M. (Tactical Rail Interface, Modular) AR rail has been designed by the Wilson Combat engineering team to be among the lightest, strongest and most versatile compact free-floating rail systems on the market.

Light, strong and easy to install-the Wilson Combat T.R.I.M. AR-15 rail interface solves multiple installation issues our gunsmiths have encountered with other rail systems in over 10 years of building thousands of our custom AR-15 rifles. The entire T.R.I.M. interface can be easily end-user installed in five minutes with common hand tools and can be quickly removed or replaced with a different length rail interface in the field with nothing more than a hex key.

The T.R.I.M.'s attachment points enable the end-user to quickly position the supplied modular Picatinny rail panel on the attached interface in pre-specified locations. A generous inside diameter of 1.47" accepts low profile gas blocks and many of the available piston gas systems. Integral push-button Q.D. sling swivel attachment points are located on both sides of the T.R.I.M. for the ultimate in sling mounting versatility.
